The Insert Datasource dialog appears when the Table button is selected in the Home Tab, and allows inserting new data sources from the available connections.

 

 

The Connections drop-down allows selecting the connection to select the data source from.

The Tables section shows a listing of the available data sources, sorted by type.

Clicking on a specific data source will bring up its fields in the Fields section. There you can check the fields you want to include and uncheck the irrelevant ones.

The Add SQL button brings up the SQL Query Editor which allows adding a custom SQL statement as a data source. Once added, the query will show up in the SQL Statements sub-list.

You can edit the query after adding it using the Edit SQL button.
